Ultra Rollz Spiral-Machine

The Ellitone UltraRollz Spiral-Machine is an analog synthesizer that rewards those who go deep. Based on the concepts presented by Peter Blasser in the Ciat-Lonbarde Rollz-5 Drum Machine, the URSM is the ultimate tool for exploring transistor chaos. A gold-plated spiral in the center comprised of 28 individual ‘Nodes’ becomes a patch bay for diving into the endless realm of textural chaos. 

How it works: the 28 ‘nodes’ within the center spiral are arranged into groups of 3 and 4 nodes (we will call these node groups ‘segments’). Each of these 8 segments is a self-contained nodal oscillator. The speed of each nodal oscillator is preset and gradually gets slower as you move farther out from the center of the spiral. These nodal oscillator segments will happily produce their own predictable stable waveforms when left alone, the magic of URSM starts when you begin cross-patching these nodal oscillators  together, thus effecting the behavior of both oscillators. There are simply no wrong connections here, any node can be connected to any other node within the spiral. Other than the included patching wires, any conductive object or material can be used inside the spiral to connect the nodes together (even your own fingers). 

Audio from the transistor spiral then travels into a pair of ultra-sonic filters arranged in stereo. These filters are controlled by the two large wooden dials located on either side of the spiral. These special filters are designed to take the ultra-sonic frequencies created by the transistor spiral and translate them back into the audio range using an audio phenomenon known as ‘heterodyning’ - (the production of a lower frequency from the combination of two almost equal high frequencies). 

The final Left/Right audio output from the ultra-sonic filters travel into an audio mixer with provided potentiometer controls for output Gain on each channel. This allows you to create a mix of the two ultra-sonic filters or isolate each side independently. Next to these 2 gain knobs are wooden buttons that select and route different segments of the center spiral oscillators into the ultra-sonic filters. 

-Final stereo audio is output to a 3.5mm (1/8th inch) stereo headphone jack.

The URSM is powered by +9v DC center positive. A 9v usb inc
